A curtain descends

June 11, 2009Siphonophores, relatives of jellyfish made of compound units, drift in the endless space
of
the open ocean. Their many tentacles, studded with batteries of
stinging cells, form a beaded curtain of deadly
fishing lines to catch prey. Researchers found this foot-long
siphonophore (Rosacea) in the Sargasso Sea, on a 2006 cruise on the NOAA ship R/V Ron Brown to catalogue
planktonic animals and sequence their DNA—part of the Census of Marine Zooplankton project.
